There is no port forwarding option on my Netgear extender

I actually did not understand anythign at all from what your'e saying. But i'll try to understand you're question's.

I attached a screenshot, thats the menu i have. I searched thrugh all of the components on the left side but i cant find a port forwarding option. To explain the router stuff agian, I have 2 router's that are the same brand and model. But 1 acts as the main router where all the internet starts and is connected to the modem (not sure what you call the device but it has to be there for the router to work). The second one is literally the same brand and model but my ISP made it act as another network access point or basically an extender. The third device i have is the netgear wn2500 that I am talking about. I made some port forwarding changes on my first and main router but i am asking if i could do the same with my netgear device but the option "port forwarding" is not even on the list. See the screenshot. Your'e question and answer are very hard to understand.
